2 Initial Operation
This description for initial operation refers to those issues that must be considered with respect to the power
supply ENT-DC. Information with respect to operation of the peripherals connected to the ENT-DC power
supply can be found in the appropriate manual.
For operation proceed as follows:
 Switch off system or machine.
 Make sure that the assembly area is non-hazardous during the initial operation in case voltages are wired or
devices will be opened that are not intrinsically safe.
 Connect Exi power supply ENT-DC. Refer to the chapter “Wiring” for the appropriate connections.
 Connect protective ground wire to the power supply ENT-DC.
Warning
The protective ground wire runs along the housing. The
housing itself must be grounded. The wire for
connecting to ground must have a cross section of at
least 2.5 mm² and should be as short as possible.
 Connect power supply.
 Verify all functions.
 Switch on system or machine.
 Verify functions of the entire system or machine.
Warning
In case the ENT-DC has not been connected correctly
or its configuration is incorrect, malfunctioning of your
system/machine is possible.
Warning
The power supply ENT-DC is exclusively designed to
be integrated into a different machine. Operation may
not be initiated until conformity of the final product with
regulation 89/336/EC and 89/392/EC has been
established and the unit has been approved by a
specialist according to EN 60079 and EN 50014
respectively.

3 ENT-DC Power Supply
The Exi power supply ENT-DC can be used in safe areas as a power supply for components in zone 1 and
zone 2. The ENT-DC provides up to 3 feed circuits and one 20 mA CL-interface. The ENT-DC can used to feed
all hazardous components which meet the interface specifications of the ENT-DC.

3.3 Pin Assignment
For the top hat rail and full housing version of the ENT-DC-2 all connections are made in the front. For the 19"version connections can be made in the front and in the rear. All connections can be reached from the front and
the back.
The connections X2, X3 and X4 are carried out as terminal screw-/plug-in terminals. The connection X1
constitutes a D-Sub jack. If the power supply operates with one feed circuit the connection X3 has four contacts.
If 2 or 3 feed circuits are in use the connection X3 has 8 contacts.

3.4 Wiring
All connections for the ENT-DC are made in the front.
All clamps are also directed to the 19” header for the 19" flush type version. Hence connections can be made in
the rear or combined in front and rear.
Note
If connections are made in the front and rear the same
signals should not be assigned in the front and rear at
the same time. Proper operation of the ENT-DC may be
endangered in this case. (Issues with respect to safety
are not impacted).

For the ENT-DC-30 is an active bus data fixing necessary. In every ENT-DC-30 there is the possibility for an
appropiate termination. For this the jumper J8 has to be put on position 2-3 and J9 put on position 1-2. The
ENT-DC-30 which are in the midth of the bus the termination has not to be done ( J8 in position 1-2 and J9 in

3.4.5 Fuses
SI 1
2 A slow blowing (type H 1500 A )
Warning
The fuse SI 1 is safety relevant. Always use the correct
type fuse.
The fuse SI 1 is melted by an internal protection circuit of the ENT-DC if the supply voltage (24 VDC) increases
to values above 32 V. This feature is safety relevant to protect the internal circuit from overloads.
Warning
The fuses SI 2 through SI 4 (round fine-wire fuses) may
not be removed nor replaced.
A defect in these fuses is unlikely.

3.4.13 Potential Equalization / Grounding
The ENT-DC must be connected to a potential equalization at a PA-clamp (X2.1 X2.3). If 19" flush-type versions
are used potential equalization is accomplished through a screw connection with the 19" rack. The 19" rack
must be connected with PA.
The intrinsically safe interface X3 may not be connected to potential equalization in the safe area which means
that the shield of the line from the hazardous area may not be applied in the safe area. Refer to regulation VDE
0165.
The data line to interface X1 must be shielded due to interference reasons. The shield must be applied on the
ENT-DC side on PA. (PA via connector housing / jack).
It is not necessary to shield the supply line (24V) to interface X2. An optional shield can be placed onto PA via
X2.1.

3.6 Instructions for Installation
Attention
To avoid heat traps in the ENT-DC-30 a minimum
distance to other components is required.
The ENT-DC-30 must be installed so that the cooling
fins either point up or down.
 Other components can be placed closely to the sides of the ENT-DC-30.
 A minimum distance of  30 mm to other components must be maintained above and below the ENT-DC.
 This minimum distance holds for all housing versions -19K, -19E, -HS, -AB
